Machine for sizing hat-bodies

MACHINE FOR SIZING HAT-BODIES.

Specication of Letters Patent No. 20,602, dated June 15, 1858.

To all whom 'it may concern.'

Be it known that I, S. IV. VVooD, of the city of l/Vashington andDistrict of Columbia, have invented certain new and useful Improvementsin Mechanism for Sizing or Flanking Hat-Bodies, of which the followingis a full, clear, and exact description, reference being had to theaccompanying drawings, making part of this specification, in which-Figure l, represents a view in perspective. Fig. 2, is a side elevationshowing the adjustable journal boxes. Fig. 3 is a side elevation of amodified form with a stationary casing.

'Ihe nature of my invention consists in sizing or planking hat bodies byrolling the bat continuously forward between endless belts running inopposite directions, with different and variable speeds.

Like letters indicate similar parts in all the figures.

To enable others skilled in the art to make and use my improvedmechanism for sizing or planking hat bodies, I will proceed to describethe same in detail.

A in the accompanying drawings represents the frame constructed of metalor wood, and of any required size and form. In this frame are arrangedany number of adjustable rollers (B) over which endless belts (D)operate; these belts are of any suitable material but for the benefit ofthose who may use their invention I would name coarse linen as beingpeculiarly adapted, which will resist without shrinking or stretching,hot water into which the bodies are frequently immersed during theprocess of sizing or planking. These endless belts may be operated bybands (C) and pulleys (It), the bands being so arranged as to operatethe two corresponding belts in opposite directions. In order that thebat (c) may be carried from the end where it is introduced anddischarged at the opposite end, the pulleys (R) vary in size whichimparts to the endless belts, between which the bat passes, variablevelocities, which causes the bat to roll or travel from end to end ofthe belts. The difference in the velocities of these endless belts maybe' governed by cone pulleys, according to the amount of work necessaryto give different kinds of material.

Fig. 2, represents a machine consisting of three endless belts, themiddle belt (F) being stationary in its bearings while the upper belt(G) and the lower belt (D) are adjustable by means of sliding journalboxes (z') these beltsare rendered adjustable so that any sized bat maypass between desired. In Fig. 2, the upper belt (G) and lower belt (D)run with equal velocity, while the middle belt (F) varies by having aslower motion; the exact arrangement of these belts and their velocitiesis of no consequence, so long as the bat rolls or travels from end toend and is discharged from the opposite end at which it was introduced.

The operation of the three endless belts, as represented in Fig. l, isas follows. The bat (e) is introduced between the upper and middle belts(G) and (F) and is rolled from left to right and discharged upon theboard (0) where the bodies are examined if necessary, when the bat (e)is introduced between the middle and lower belts (F) and (D) rollingbetween them and discharged (S). This operation is repeated until thebodies are sized or planked. The arrows in red represent the directionof the bats, and the arrows in black show the direction the belts aremoving.

Having thus fully described my improved mechanism for sizing or plankinghat bodies, what I claim therein as new and desire to secure by LettersPatent is Sizing or planking hat bodies, by rolling the bat continuouslyforward, that is to say, in one direction between endless belts runningin opposit-e directions and at different or variable velocities, asherein specified.
